[T3] Clean oil cooler?

[Jon Stiles]

It is safe to clean out an oil cooler with solvent. compressed air should be used to dry out and expel the solvent. I prefer a solvent with a high evaporation rate like xylene, lacquer thinner or a high quality carb cleaner.

I remove the oil pressure sending unit to keep solvent off of the plastic casting and clean it separately.

Type 1 coolers are identical to Type 3 coolers with the exception of the oil pressure location. Type 1 coolers have the boss cast into their design to be used with a type 3 oil pressure sending unit. They can be easily drilled and tapped if purchased new.

Caution should be used to keep any aluminum filings out of the radiator rows.
